Flying with my Dad

My Dad rode his Harley up on Tuesday to come for a visit. We had a great time hanging out and running errands. On Wednesday we tried to fly him up to Quincey for breakfast, but guess what? The plane didn't start, we tried to take both of parents flying last time they came up but we had to turn around and make an emergency landing when we had and exhaust problem. Everything is okay, but we're beginning to think my Dad and the plane don't mix!
